Watch Elizabeth Warren's Speech in Defense of Planned Parenthood

Senator Elizabeth Warren has criticized members of Congress who want to defund Planned Parenthood.

"Do you have any idea what year it is?" Warren asked, speaking before Monday's Senate vote on the defunding bill. "Did you fall down, hit your head and think you woke up in the 1950s or the 1890s? Should we call for a doctor?"

Warren was speaking after covertly recorded videos released by the Center for Medical Progress showed Planned Parenthood officials discussing the costs associated with fetal-tissue extraction. That footage, roundly criticized by both parties, set off a political firestorm, with Republicans alleging that the conversations proved that staffers were selling baby body parts for profit.

Senator Joni Ernst introduced a bill involving the sweeping defunding of the organization, in a bid to hit back against what, in a recent TIME op-ed, Ernst and Senators Rand Paul and James Lankford called "callous actions that strike at the moral fabric of our society."

In response, Planned Parenthood has maintained that the videos were taken out of context and alleges that they were edited.

The Senate later voted down the bill, but the issue is expected to resurface as Congress attempts to pass spending bills later in the year.
